Josh Elser resolved ACCUMULO-4035.
----------------------------------
Resolution: Fixed
> Spurious NamespacesIT.verifyConstraintInheritance failure
> ---------------------------------------------------------
>
> Key: ACCUMULO-4035
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4035
> Project: Accumulo
> Issue Type: Bug
> Components: test
> Reporter: Josh Elser
> Assignee: Josh Elser
> Priority: Minor
> Fix For: 1.6.5, 1.7.1, 1.8.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> {noformat}
> java.lang.AssertionError: null
> at org.junit.Assert.fail(Assert.java:86)
> at org.junit.Assert.fail(Assert.java:95)
> at
> org.apache.accumulo.test.NamespacesIT.verifyConstraintInheritance(NamespacesIT.java:516)
> {noformat}
> Which lines up with the following code, the assertion failure happening on
> the {{fail()}}
> {code}
> c.namespaceOperations().addConstraint(namespace, constraintClassName);
>
> assertTrue(c.namespaceOperations().listConstraints(namespace).containsKey(constraintClassName));
>
> assertTrue(c.tableOperations().listConstraints(t1).containsKey(constraintClassName));
> int num =
> c.namespaceOperations().listConstraints(namespace).get(constraintClassName);
> assertEquals(num, (int)
> c.tableOperations().listConstraints(t1).get(constraintClassName));
> // doesn't take effect immediately, needs time to propagate to tserver's
> ZooKeeper cache
> UtilWaitThread.sleep(250);
> Mutation m1 = new Mutation("r1");
> Mutation m2 = new Mutation("r2");
> Mutation m3 = new Mutation("r3");
> m1.put("a", "b", new Value("abcde".getBytes(UTF_8)));
> m2.put("e", "f", new Value("123".getBytes(UTF_8)));
> m3.put("c", "d", new Value("zyxwv".getBytes(UTF_8)));
> BatchWriter bw = c.createBatchWriter(t1, new BatchWriterConfig());
> bw.addMutations(Arrays.asList(m1, m2, m3));
> try {
> bw.close();
> fail();
> } catch (MutationsRejectedException e) {
> assertEquals(1, e.getConstraintViolationSummaries().size());
> assertEquals(2,
> e.getConstraintViolationSummaries().get(0).getNumberOfViolatingMutations());
> }
> {code}
> Looks like this is just another case where a test poorly makes assumptions
> about ZK propagation.
